The essence of the technical solution of the embodiment of the present invention is further clarified by specific examples below.
The intelligent devices in the embodiments of the present invention, such as smartwatches, mobile phones, smart homes, and the like, all support Round Trip Time (RTT) technology wireless networks, such as WiFi, bluetooth, and the like. In the common wireless network environment, each intelligent device can be used as a basis for data transmission, and based on the RTT technology, distance measurement and angle measurement of each intelligent device can be realized, and based on the measurement and measurement results, the system can accurately transmit an instruction according to the measurement and measurement results as long as a user points the hand with the watch to the device direction (such as a computer in a study room) to which the instruction is to be transmitted after the user sends the instruction (such as a voice instruction). Examples are as follows:
smart devices such as smart watches, mobile phones, and other smart devices are all connected to the same network environment, such as a WiFi or bluetooth environment;
first intelligent portable devices such as smart watches, mobile phones and the like utilize RTT to locate other intelligent devices in the network, including distance information and angle information. The assistance uses a compass, a Global Positioning System (GPS), an electronic compass, a gyroscope, or a gravity acceleration sensor device to generate an angle with the reference direction and calculate which smart device the first smart portable device is pointing at this time. Then an instruction is sent, for example by voice: and (5) playing the gray girls.
The second intelligent device receives an operation instruction sent by a user by using the first intelligent portable device, analyzes the operation instruction and then executes the operation instruction, for example, the second intelligent device supports a music playing function, the operation instruction can be a song playing function, at the moment, the second intelligent device receives the operation instruction, analyzes that the instruction contains a song name, and starts the player to play a corresponding song.
The embodiment is based on a wireless RTT network, etc., and a sensor capable of generating an angle with respect to a reference direction, such as a compass, a GPS, an electronic compass, a gyroscope, a gravity acceleration sensor, etc., determines the orientation of another smart device, and sends an operation instruction to a second electronic device in a set orientation of a first smart device, so that the second smart device executes the operation instruction. Only the first smart device with remote control function needs to have the aforementioned sensor, for example, in this case, the first smart device may be a smart band, or a watch, etc., which has the capability of calculating the orientation of other smart devices.
As shown in fig. 2, in the embodiment of the present invention, the position of the second smart device relative to the first smart device is mainly determined by a triangle formed between the two second smart devices and the first smart device. As shown in fig. 2, the intelligent devices A, B, C form a triangle, and specifically, the distance between the intelligent devices AB, AC, and BC can be calculated by the wireless RTT technique, and the included angle between the three devices can be obtained according to the distance.
If there is only one second intelligent device except the first intelligent portable device sending commands, such as a smart watch and a mobile phone, in the WiFi or bluetooth network, the second intelligent device does not need to be located, and all commands of the first intelligent device are defaulted to be sent to the only second intelligent device in the current WiFi or bluetooth network.
When there is more than one intelligent device in the WiFi network except the first intelligent portable device sending the command, as shown in fig. 3, the first intelligent device O may perform positioning calibration according to any two second intelligent devices (device a and device B) in the network, and first, according to the current position, the distance and angle of the first intelligent device O, the device a, and the device B are calculated by using the WiFi RTT function, so as to obtain a triangle formed by the device a, the device B, and the first intelligent device O, where the size and the shape of the triangle are determined, but the position is not fixed, and the position may be in any direction rotating 360 degrees around the device O. Thus, if the device A, B needs to be accurately located, the first smart device O needs to change its position, and then the triangle formed between the first smart device O and the second smart device A, B is determined, so that the second smart device A, B can be accurately located. Specifically, the user may be prompted to move the mobile intelligent portable device a distance m along its set direction, for example, due north, wait for the WiFiRTT to measure the new position, and thus measure a new triangle formed by the three intelligent devices, as shown in fig. 4.
Because the determined size and shape of the triangle are determined, and the included angle between OO' and the true north of the physical direction can be known through the positioning equipment such as the compass on the first intelligent equipment O, the distance between the equipment AB and the intelligent portable equipment O and the included angle between the equipment AB and the pointing direction of the equipment AB can be determined according to the included angle θ and η twice before and after the movement between the OABs, that is, the equipment a and the equipment B are positioned.
The portable intelligent device is used as an origin, a dynamic virtual coordinate system is established by taking the direction pointed on the intelligent device as a real axis, as shown in fig. 4, when the first intelligent device is at the point O, the sizes of theta, AO and BO can be measured, and when the first intelligent device moves to the point O ', the sizes of η, AO ' and BO ' can also be measured.
In the embodiment of the invention, any two second intelligent devices and the first intelligent device can form an RTT triangle, so that all devices in the WiFi network can be positioned. In the embodiment of the invention, the distance between the intelligent devices can be determined by the transceiving time delay of wireless signals between the intelligent devices and the like.
In the embodiment of the invention, for the convenience of calculation, the first intelligent device is used as an original point, and the set direction is used as a coordinate system real axis to establish a coordinate system.
After the coordinate system is established, the first intelligent device performs position calibration on the rest second intelligent devices, and records coordinates of all the second intelligent devices in the wireless network. In the embodiment of the present invention, the second smart device may be positioned in a manner of constructing a triangle as described above.
After the first intelligent device is awakened from sleep, the RTT is used for measuring the distance and the angle between the first intelligent device and any two devices so as to determine the change of the position of the first intelligent device, and all second intelligent devices in the network move oppositely relative to the first intelligent device (because the coordinate system always uses the first intelligent device as an origin), so that the coordinate updating is carried out on all devices in the wireless network. In the embodiment of the present invention, it is assumed that the second smart device is a stationary device, that is, most of the second smart devices are smart homes and other devices, which are inconvenient to carry and do not need to carry, so that a user is generally inconvenient to perform short-distance operations on the smart homes, and therefore, a control instruction and the like need to be generated on the smart homes by means of the first smart devices such as a mobile phone.
When a new second intelligent device joins the network, the portable intelligent device can form two triangles according to any two intelligent devices in the network and the newly joined device, so that the coordinates of the newly joined intelligent device relative to the coordinate system of the portable intelligent device are obtained, and the newly joined intelligent device is positioned.
When the pointing direction of the portable intelligent device is changed, the coordinates of all devices in the wireless network can be changed (only the angle is changed), the portable intelligent device can update the coordinates (the included angle and the distance between the portable intelligent device and the real axis) of all intelligent devices in the wireless network, a device with the smallest included angle is selected from devices with the included angle (namely the angle component of the device coordinate) smaller than 30 degrees or other thresholds (specifically set by a user) to serve as the device pointed by the portable intelligent device (a mobile phone and a watch), when more than one device with the smallest included angle is arranged, the device close to the device is selected according to the distance, and if the included angle distances are the same, the user is prompted to move the position of the portable intelligent device, or the device required to be pointed is selected by the angle. In the embodiment of the invention, the set direction of the first intelligent device is used for determining the object to be sent by the first intelligent device. In the embodiment of the present invention, all the second smart devices whose set direction of the first smart device is smaller than the set threshold angle are used as objects to which the first smart device intends to send the control command, where the set threshold angle may be 1 degree, 5 degrees, 10 degrees, or 30 degrees. When there are a plurality of second smart devices in the setting direction of the first smart device, the plurality of second smart devices may all be used as control instruction receivers, and the second smart device that receives the control instruction determines whether the control instruction sent by the user is sent to itself by identifying the received control instruction. Of course, it is preferable that the user of the first intelligent device is notified to select one of the second intelligent devices as the receiving party of the control instruction when there are a plurality of second intelligent devices for setting the pointing direction, or one of the second intelligent devices is determined as the receiving party of the control instruction according to the size of the angle with the set pointing direction.
The method for positioning according to the triangle formed by the smart device according to the embodiment of the present invention is further explained with reference to fig. 6. The specific positioning principle is as follows:
with O as the origin, the pointing direction of the portable intelligent device (first intelligent device) is used as the real axis to establish a virtual coordinate system, the coordinates of the device a and the device B before moving the portable intelligent device are respectively (AO, <tttranslation = α "&tttα &/t >t) and (BO, <tttranslation = β" &tttβ &/t >t), and after moving to O ', the coordinates of the device a and the device B become respectively (AO ', α ') and (BO, <tttranslation = β "&tttβ &/t >t '), and according to the triangular relationship, the coordinates of the device a and the device B become respectively (AO ', α ') and (BO <tttranslation &/t &/gtt '), the triangular relationship is known
(xA)2+(yA)2＝(OA)2
(xB)2+(yB)2＝(OB)2
(xA′)2+(yA′)2＝(O′A)2
(xB′)2+(yB′)2＝(O′B)2
xA-|0O′|＝xA′
xB-|0O′|＝xB′
The dynamic coordinates of the device a and the device B in the coordinate system of the first smart device, namely the distances between the device a and the device B and the portable smart device and the included angles between the device and the portable smart device can be solved by the above equations.
When the second intelligent equipment is positioned, the positions of the two pieces of second intelligent equipment to be positioned are fixed, and if the positions of the two pieces of second intelligent equipment used in the positioning period are changed, although the positioning can be obtained, the positioning result can deviate from the actual position.
When a user needs to operate the equipment in the wireless network, the user only needs to point the intelligent equipment to the equipment and then send an operation command through application, such as turning on and off a lamp, turning on and off a television, turning on and off an air conditioner and the like.
The essence of the technical solution of the embodiments of the present invention is further clarified below by providing examples of several application scenarios.
In the case of multiple second smart devices facing a home, if the second electronic device is controlled by voice, a control object needs to be spoken, such as a voice command: the television plays song gray girl (a plurality of televisions in the family are more difficult to express), or walks to the front of the corresponding second intelligent equipment, and speaks a voice instruction to the second intelligent equipment: playing the physalis alkekengi; and the corresponding second intelligent equipment can output the music to be played to the user after a series of processes such as film searching, cache preparation and the like. If a first smart device such as a smart watch sends a control instruction, a voice instruction can be input to the first smart device such as a wearable device such as a smart watch at a place far away from a second smart device: and playing the girl and then pointing to the direction of the second intelligent device to be played, sending a control instruction to the second intelligent device, and enabling the user to watch the second intelligent device again until the second intelligent device starts playing.
